Custom ringback tone systems and methods

ABSTRACT

A ringback tone service may be configured by determining an indication to suggest one or more callers to a user of a mobile-telephony device and obtaining historical call data describing recent calls placed by recent callers to the mobile-telephony device in a recent period of time. After identifying a number of frequent callers for whom no custom ringback tone is currently provisioned, the user is prompted to select from a list of custom ringback tones that are available to provision for incoming calls from the frequent caller(s). In some cases, the user may send a message to the caller, allowing the caller to select his or her own custom ringback tone via a user interface provided by a ringback tone-service provider.

FIELD

The present disclosure relates to the field of mobile communications, and more particularly, to providing custom ringback tones to callers of mobile users.

BACKGROUND

A ringback tone (or ringing tone) is an audible indication that is heard on the telephone line by the caller while the phone they are calling is being rung. It is normally a repeated tone, designed to assure the calling party that the called party's line is ringing, although the ring-back tone may be out of sync with the ringing signal.

The ringback tone is in most cases generated in a distant switch and transmitted in-band. The distant switch also sends a message out band indicating to the rest of the following network that the phone is ringing. In most public phone networks today the ringback tone is not generated in the handset or by the local switch, as customized tones or voice announcements may be generated by the distant switch in place of a ringing signal.

Some carriers allow a subscriber to customize the ringback tone heard by some or all callers to the subscriber, such that when a caller calls the subscriber, the caller does not hear the normal repeated tone, but instead hears music, a message from the subscriber, or other recording.

However, it is not necessary to show such infrastructure and implementation details in FIG. 1 in order to describe an illustrative embodiment.

FIG. 2 illustrates an exemplary series of communications between callee device 1100, caller device 120, ringback tone server 1200, and carrier server 130 in accordance with one embodiment. The communications shown in FIG. 2 do not encompass every combination of possibilities in which the systems and methods provided herein may be employed. Rather, the illustrated communications merely provide an overview of one simplified example scenario. Additional variations and alternatives are described more fully in the Figures and description that follow.

Beginning the illustrated sequence of communications, callee device 1100 determines 204 an indication to suggest one or more callers to a user.

Callee device 1100 obtains 208 historical call data or “call history” describing recent calls placed by recent callers to callee device 1100 in a recent-past period of time (e.g., the past few months).

Callee device 1100 identifies 212 one or more frequent callers (including caller device 120) among the recent callers.

Callee device 1100 determines 216 that no custom ringback tone is currently provisioned for caller.

Callee device 1100 sends to ringback tone server 1200 a request 220 for one or more custom ringback tones that the user of callee device 1100 has purchased or that are otherwise available for the user's use.

Ringback tone server 1200 processes 224 the request and sends to callee device 1100 one or more identifiers 228 identifying the requested custom ringback tones that the user of callee device 1100 has purchased or that are otherwise available for the user's use.

Callee device 1100 prompts 232 the user to select one of the available ringback tones as a custom ringback tone to provision as a custom ringback tone for calls placed by caller device 120 to callee device 1100.

In many cases, the user may select one of the ringback tones, but in the exemplary scenario, the user indicates 236 that the caller should select a ringback tone that he or she would like to hear when he or she places a call to callee device 1100.

Callee device 1100 sends to ringback tone server 1200 a request 240 to provide a user interface (“UI”) (e.g., via the web) by which the caller can select a custom ringback tone.

Ringback tone server 1200 processes 244 the request and sends to callee device 1100 a URI, URL, or other UI identifier 248 by which the caller can access a ringback-tone-selection UI.

Callee device 1100 generates 251 a message for the caller, the message including the identifier 248 received from ringback tone server 1200.

Callee device 1100 sends to carrier server 130 a request 255 to deliver the generated message to caller device 120 and/or to notify the caller device 120 (e.g., via a push notification) that the generated message is available.

Carrier server 130 processes 259 the request and sends to caller device 120 (e.g., via a text message and/or push notification) a message prompting the caller to access the custom-ringback tone-selection UI.

Caller device 120 presents 267 the message to the caller, who indicates (not shown) a desire to access the custom-ringback tone-selection UI.

Caller device 120 sends to ringback tone server 1200 a request 271 to access the custom-ringback tone-selection UI.

Ringback tone server 1200 processes 275 the request and sends to caller device 120 data (e.g., HTML data) comprising the custom-ringback tone-selection UI.

Caller device 120 presents 283 the custom-ringback tone-selection UI to the caller, who indicates (not shown) a selection of an available ringback tone.

Caller device 120 sends to ringback tone server 1200 a ringback tone selection 287 indicating that the caller has selected one of the available ringback tones.

Ringback tone server 1200 sends to callee device 1100 an indication 291 indicating that the caller has selected a custom ringback tone.

Ringback tone server 1200 sends to carrier server 130 a request 295 to provision the selected ringback tone. In other embodiments, callee device 1100 may send request 295 to ringback tone server 1200 and/or carrier server 130.

Carrier server 130 provisions 299 the requested ringback tone such that the caller will hear the selected ringback tone for calls placed to callee device 1100.

FIG. 3 illustrates a ringback-tone-configuration routine 300 for configuring a ringback tone service, such as may be performed by a callee device 1100 in accordance with one embodiment.

In block 305, ringback-tone-configuration routine 300 determine an indication to suggest one or more callers to a user of a mobile-telephony device (e.g., callee device 1100). For example, in one embodiment, ringback-tone-configuration routine 300 may execute as part of a ringback tone-service application installed on a mobile-telephony device. In some embodiments, ringback-tone-configuration routine 300 may determine such an indication as part of a setup process when the application is installed. In other embodiments, ringback-tone-configuration routine 300 may execute on a periodic basis and/or upon request from a user.

In block 310, ringback-tone-configuration routine 300 obtains a call history describing recent calls placed by recent callers to the mobile-telephony device in a recent-past period of time, such as the previous few weeks or months.

In block 315, ringback-tone-configuration routine 300 identifies one or more ringback tones that are available for use by the user of the mobile-telephony device on which ringback-tone-configuration routine 300 is executing. For example, the user may have purchased one or more ringback tones to make them available. In some embodiments, identifying available ringback tones may include querying ringback tone server 1200.

In subroutine block 400, ringback-tone-configuration routine 300 identifies, based at least in part on the call history obtained in block 310, one or more frequent callers among the recent callers identified in block 310.

Beginning in opening loop block 325, ringback-tone-configuration routine 300 processes each frequent-caller in turn.

In decision block 330, ringback-tone-configuration routine 300 determines whether a custom ringback tone is currently provisioned for the current frequent-caller. If so, then ringback-tone-configuration routine 300 proceeds to ending loop block 350. Otherwise, ringback-tone-configuration routine 300 proceeds to block 335.

In block 335, ringback-tone-configuration routine 300 prompts the user to select an available ringback tone to provision as a custom ringback tone for calls placed by the current frequent-caller to the mobile-telephony device on which ringback-tone-configuration routine 300 is executing.

In subroutine block 500, ringback-tone-configuration routine 300 obtains an indication selecting an available ringback tone.

In block 345, ringback-tone-configuration routine 300 provisions the selected ringback tone for incoming calls from the current frequent-caller.

In ending loop block 350, ringback-tone-configuration routine 300 iterates back to opening loop block 325 to process the next frequent-caller, if any.

Ringback-tone-configuration routine 300 ends in ending block 399.

FIG. 4 illustrates a frequent-caller-identification subroutine 400 for identifying frequent callers given a call history of a given mobile-telephony device, such as may be performed by a callee device 1100 in accordance with one embodiment.

In block 405, frequent-caller-identification subroutine 400 identifies one or more unique callers in the given call history for the given mobile-telephony device.

In block 410, frequent-caller-identification subroutine 400 sorts the unique callers identified in block 405 by a count of calls that each unique caller placed to the mobile-telephony device.

In block 415, frequent-caller-identification subroutine 400 determines a desired count of frequent callers to identify (e.g., five frequent callers).

In block 420, frequent-caller-identification subroutine 400 initializes a frequent-caller data structure (e.g., an array, list, hash, map, dictionary, or other suitable data structure).

Beginning in opening loop block 425, frequent-caller-identification subroutine 400 processes each unique caller in turn in order of descending call-count (as sorted in block 410).

In decision block 430, frequent-caller-identification subroutine 400 determines whether the current unique caller is in an address book, contact list, personal information manager, friend list, or other similar list of contacts and/or persons who are known to a user of the given mobile-telephony device. In various embodiments, such an address book (or the like) may be stored on the given mobile-telephony device; on a desktop, laptop, or similar computing device associated with the given mobile-telephony device; and/or on a remote server device accessible via a network (e.g., data network 110).

If so, frequent-caller-identification subroutine 400 proceeds to block 435. Otherwise, if the current unique caller is not in an address book (or the like) associated with the user, then frequent-caller-identification subroutine 400 proceeds to ending loop block 445.

In block 435, frequent-caller-identification subroutine 400 adds the current unique-caller to the frequent-caller data structure initialized in block 420.

In decision block 440, frequent-caller-identification subroutine 400 determines whether the desired count of frequent callers (as determined in block 415) have been identified and added to the frequent-caller data structure. If so, then frequent-caller-identification subroutine 400 proceeds to ending block 499. Otherwise, frequent-caller-identification subroutine 400 proceeds to ending loop block 445.

In ending loop block 445, frequent-caller-identification subroutine 400 iterates back to opening loop block 425 to process the next unique-caller, if any.

Frequent-caller-identification subroutine 400 ends in ending block 499, returning the frequent-caller data structure to the calling routine.

FIG. 5 illustrates a ringback-tone-selection subroutine 500 for obtaining a selection of a ringback tone from a given list of available ringback tones for a given caller to a given mobile-telephony device, such as may be performed by a callee device 1100 in accordance with one embodiment.

In decision block 505, ringback-tone-selection subroutine 500 determines whether to allow the given caller to select a custom ringback tone, or to obtain a selection from a user of the given mobile-telephony device. If it is determined to allow the given caller to make the selection, then ringback-tone-selection subroutine 500 proceeds to block 510. Otherwise, ringback-tone-selection subroutine 500 proceeds to block 530.

In block 510, ringback-tone-selection subroutine 500 obtains a URI, URL, or other identifier identifying a selection UI that the given caller can access to select an available ringback tone from the given list of available ringback tones. For example, in one embodiment, ringback-tone-selection subroutine 500 may request and receive the identifier from a remote ringback tone-service server (e.g., ringback tone server 1200).

In block 515, ringback-tone-selection subroutine 500 generates a message requesting the given caller to select a ringback tone via the selection UI, the message including the selection-UI identifier obtained in block 510.

In block 520, ringback-tone-selection subroutine 500 provides the message generated in block 515 for delivery to the given caller. For example, in one embodiment, ringback-tone-selection subroutine 500 may send the generated message as a text message through a carrier server (e.g., carrier server 130). In other embodiments, ringback-tone-selection subroutine 500 may send the message or cause the message to be sent via email, a social network, or other available communications medium.

In block 525, ringback-tone-selection subroutine 500 obtains an indication that the given caller has selected a custom ringback tone via the selection UI.

In block 530, ringback-tone-selection subroutine 500 obtains a ringback-tone selection from the user of the given mobile-telephony device.

Ringback-tone-selection subroutine 500 ends in ending block 599, returning to the calling routine an identifier identifying the selected ringback tone.

FIG. 6 illustrates a ringback-tone-UI request routine 600 for providing an identifier identifying a user interface by which a given caller can select a custom ringback tone from ringback tones that are available to a given callee, such as may be performed by a ringback tone server 1200 in accordance with one embodiment.

In block 605, ringback-tone-UI request routine 600 receives a request from a remote mobile-telephony device (e.g., callee device 1100) to provide a user interface by which a caller who frequently calls the remote mobile-telephony device can select a ringback tone that the caller will hear when he or she calls the remote mobile-telephony device.

In block 610, ringback-tone-UI request routine 600 generates a unique identifier to associate with the requested user interface.

In block 615, ringback-tone-UI request routine 600 associates the identifier generated in block 610 with the requested user interface (e.g., by storing and/or updating a record in database 1240).

In block 620, ringback-tone-UI request routine 600 provides the identifier to the remote mobile-telephony device.

Ringback-tone-UI request routine 600 ends in ending block 699.

FIG. 7 illustrates a ringback-tone-UI routine 700 for providing a user interface by which a requesting caller can select a custom ringback tone from ringback tones that are available to a given callee, such as may be performed by a ringback tone server 1200 in accordance with one embodiment.

In block 705, ringback-tone-UI routine 700 receives a request from a remote mobile-telephony device (e.g., caller device 120) including a previously-generated identifier identifying a user interface by which a caller can select a ringback tone.

In block 710, ringback-tone-UI routine 700 identifies a user-interface and a callee that were previously associated with the UI identifier received in block 705 (e.g., by using the identifier to locate a record previously stored and/or updated in database 1240).

In block 715, ringback-tone-UI routine 700 obtains a list of ringback tones to allow the caller to select from. In some embodiments, the list of ringback tones may include ringback tones that a user of the callee mobile-telephony device has purchased or that are otherwise available to that user. In other embodiments, the list of ringback tones may also include ringback tones that the user of the callee mobile-telephony device has not purchased, but that are available for the user to purchase.

In block 720, ringback-tone-UI routine 700 provides the requested ringback-tone-selection user interface to the requesting remote mobile-telephony device.

In block 725, ringback-tone-UI routine 700 obtains a ringback tone selection, via the user interface provided in block 720, of one of the list of ringback tones obtained in block 715.

In block 730, ringback-tone-UI routine 700 sends a message to the callee's remote mobile-telephony device indicating that the caller has selected a ringback tone. If the selected ringback tone requires the callee to make a purchase to make the selected ringback tone available, ringback-tone-UI routine 700 may further notify the callee that he or she can purchase the selected ringback tone.

In decision block 735, ringback-tone-UI routine 700 determines whether to provision the selected ringback tone for callee mobile-telephony device. If conditions are satisfied to provision the ringback tone (e.g., if the callee has purchased the ringback tone, and if the callee's mobile-telephony device is not responsible for provisioning the ringback tone), then ringback-tone-UI routine 700 proceeds to block 740. Otherwise, ringback-tone-UI routine 700 proceeds to ending block 799.

In block 740, ringback-tone-UI routine 700 sends a request (e.g., to carrier server 130) to provision the selected ringback tone as a custom ringback tone for calls placed by the caller to callee.

Ringback-tone-UI routine 700 ends in ending block 799.
